The S-PLUS data are accessible by a variety of means:

Data Lab Table Access Protocol (TAP) service

TAP provides a convenient access layer to the S-PLUS catalog database. TAP-aware clients (such as TOPCAT) can point to https://datalab.noirlab.edu/tap, select the splus_dr4, splus_dr2, or the splus_dr1 database, and see the database tables and descriptions. You can also view the S-PLUS tables and descriptions in the Data Lab table browser.

Data Lab Query Client

The Query Client is available as part of the Data Lab software distribution. The Query Client provides a Python API to Data Lab database services. These services include anonymous and authenticated access through synchronous or asynchronous queries of the catalog made directly to the database. Additional Data Lab services for registered users include personal database storage and storage through the Data Lab VOSpace.

The Query Client can be called from a Jupyter Notebook on the Data Lab Notebook server. Example notebooks are provided to users upon creation of their user account (register here), and are also available to browse on GitHub at https://github.com/astro-datalab/notebooks-latest.

Image cutouts

The Data Lab Simple Image Access (SIA) service provides a fast way to retrieve cutouts from S-PLUS images. See our Jupyter notebook on how to use the SIA service. For S-PLUS DR2, the SIA URL is "https://datalab.noirlab.edu/sia/splus_dr2". For S-PLUS DR1, the SIA URL is "https://datalab.noirlab.edu/sia/splus_dr1".

Jupyter Notebook Server

The Data Lab Jupyter Notebook server (authenticated service) contains examples of how to access and visualize the S-PLUS catalog:
